There are 0.499 moles present in $3.01 \times 10^{23}$ molecules of Boron trichloride.

Explanation:

According to mole concept, there are $6.022 \times 10^{23}$ molecules present in 1 mole of a substance.

Hence, number of moles present in $3.01 \times 10^{23}$ molecules are as follows.

$Moles = \frac{3.01 \times 10^{23}}{6.022 \times 10^{23}}\\= 0.499 mol$

Thus, we can conclude that there are 0.499 moles present in $3.01 \times 10^{23}$ molecules of Boron trichloride.
